Extract text from a PDF (pdf to text). API in docker.

Why did we create this project?

1. In the Laravel project, it was necessary to extract texts from large files. Existing packages do not work with files larger than 50 megabytes.
2. Text extraction is an expensive operation. Running on a separate server will reduce the load.
3. It was necessary to create a cover for the source.
